My book WN62 from Hein Severloh says the same.
Those wooden ramps were always built to serve as ramps and were fitted with crude saws or mines.
Only the simple logs with mines on top were faced outwards.
Otherwise a nice map idea. I enjoyed the FH1 beach rushing a lot
But judging from the (bad quality) screenshots, there needs to be more rubble next to the destroyed buildings. Most likely most of the bombing damage happend just one day before.
Well I just checked the area in Google Earth and i´m amazed by the details. They even have the bunkers and guns as 3D Buildings. Together with the Pics from Panoramio you can check the smallest Details and the big picture for correct scales.
Speaking of this, I think your beach is too wide compared to the real thing as its a small flat beach and a long slope in google earth. Also the second bunker row is 300 meters behind the bunker at the beach ridge. In your screens they seem to be much closer together.
How about the naval shelling, do you have plans for this? Would be nice to see a ship out there if the HMS Ajax was only 1 km away.
